Of the four globins that make up hemoglobin, two are identical and called alpha globins, and the other two are called beta globins and are also identical.
<h3>Structure of Haemoglobin</h3>
- Each of the four subunits of hemoglobin has a polypeptide chain and a heme group.
- The iron protoporphyrin IX prosthetic heme group, which is connected to a polypeptide chain with residues of 141 (alpha) and 146 (beta) amino acids, is present in all hemoglobins.
- A histidine's N is linked to the ferrous iron of the heme. A polypeptide chain phenylalanine of the porphyrin ring wedges it into its pocket.
- Alpha and beta chains, two varieties of the polypeptide chains that make up adult hemoglobin, are comparable in length but have different amino acid sequences.
- Both adult and embryonic human hemoglobins have the same alpha chain.

Answer:
the answer is a. both as a primary and secondary consumer
Explanation:
primary consumers eat producers.
secondary consumers eat primary consumers.
in this scenario, the bird fits into both categories, because it feeds on berries (producers) and plant-eating insects (primary consumers)
It is B, it could also be D, but it is most likely B. Hope this helps.
The process that is responsible for the production of glucose in plants is photosynthesis.
<h3>What is photosynthesis?</h3>
Photosynthesis is a chemical process in which organic matter is formed from inorganic matter thanks to <em>sunlight</em>, this is a process given in autotrophic organisms which are <u>capable of synthesizing their own food</u> through this process.
What happens is that thanks to sunlight, molecules are formed that contain high levels of energy (ATP and NADPH), these molecules are used for the synthesis of carbohydrates that are used to feed the cell.
Therefore, we can confirm that the process that is responsible for the production of glucose in plants is photosynthesis.
